of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to wire straightening and cutting off machines, andit consists of an arrangement of. mechanism for drivin all of therotatable parts-of the ma-' chine y means of a single belt drivedirectly from the straightening arbor.

The object of my invention is to eliminate a plurality ofthecountershafts, pulleys and gears heretofore employed on machines of thischaracter, besides enabling the machine head to be greatly reduced inwidth and a. corresponding reduction in the cost of construction.

Referring to the drawings wherein the same figures of reference indicatelike parts throughout the several views: Figure 1 represents a sideelevation of the machine head, broken view of the base, rock shaft anduide bar; and Fig. 2 is an end view looking in the direction of arrow aof Fig. 1.

The straightening arbor 1, journaled in the projections 2 of the head 3,carries the worm 4 meshing with the large gear 5 secured to thetransversely located driving shaft 6 journaled in the machine head 3 andthe bracket 7 integral with the head.

8 is a large spur gear mounted on the projecting end of the drivingshaft and it meshes with the gear 9 on the projecting end of the lowerfeed roll shaft 10, andalso with the large gear 11 on the cam shaft'12.The upper feed roll shaft 13 is rotated, as usual from'the lower feedroll shaft-through the I medium of the pinions 14, 15. These shaftscarry the usual feed rolls 16, 17.

The large gearvll on the cam shaft 12 serves the same purpose as theusual balance wheel pulley and runs idle during the time the properlength of wire is being .fed forward by the feed rolls. The movement ofSpecification of Letters Patent.

the cutting off lever 18, mounted on the rock shaft 19 and carrying theusual guide bar 20, is accomplished in the usual manner by means of thekey 21, clutch lever 22, cam 23, roll 24 mounted on the pin 25 securedto the lower end of the cutting off lever. The wire 26 on the :end ofthe clutch lever connects with the usual mechanism (not shown) fortripping said lever and setting the cutting off mechanism in operationwhen the predetermined length of wire has been fed forward. The usualmanual tripping mechanism comprises the rod 27,-lever 28 and handlelever 29 attached to saiclrod.

30 is a pulley integral with the strai htening arbor 1, and said arboris rotated by a belt (not shown) adapted to connect said pulley withoverhead driving mechanism (not shown). This belt is the only one usedin connection with the machine. All of the as before mentioned, arerotated directly from the straightening arbor, thus avoiding the use ofa plurality of belts and giving a more uniform and positive drive.

i The gears are so constructed as to their diameters and the properworking speed developed so that the gear on the cam shaft can be madelarge enough to serve the purpose of a balance wheel, thus avoiding theexpense of mounting an extra balance on said shaft and belt to drive thesame.

Having thus described my invention, what I claim is In a machine of thecharacter described having ahead, a straightening arbor rotatablymounted therein, feed rolls, and a cam shaft for actuating a cutting offlever, a

, worm mounted on the straightening arbor,

a driving shaft j ournaled transversely in the head, a worm gear on oneend of said shaft meshingwith said worm, a train of gears connectlng thedriving shaft, one of the feed roll shafts and cam shaft, the gearon'said cam shaft adapted to run free'during the wire feeding operation,and means for connecting said gear with the cam shaft.

In testimony whereof I afiix my signature in presence of two witnesses.
